Medium-chain-length polyhydroxyalkanoates (MCL-PHAs) were produced in carbon-limited, single-stage, fed-batch fermentations of Pseudomonas putida KT2440 by co-feeding nonanoic acid (NA) and glucose (G) to enhance the yield of PHA from NA. An exponential (mu=0.25 h(-1)) followed by a linear feeding strategy at a NA:G ratio of 1:1 (w/w) achieved 71 g l(-1) biomass containing 56% PHA. Although the same overall PHA productivity (1.44 g l(-1) h(-1)) was obtained when NA alone was fed at the same… CONTINUE READING
